From the time the notion "embodied cognition" has entered the field, researchers have been concerned about its meaning. Does the term refer to a coherent theoretical framework? Despite these concerns, use of the term "embodied cognition" has increased over the years to plateau in recent years. I will argue that the best way forward is not to search for evidence for or against some vague label but rather to systematically, in large-scale projects, address a series of questions that focus on well-defined cognitive tasks. Such projects ought involve preregistration, replication, and open materials, code, and data. For this enterprise to take off, it is important that incentives in the field be aligned with the goal to increase the reliability and validity of our research. There is reason to be optimistic that such an alignment will occur in the near future.Delayed coronary obstruction after transcatheter aortic valve implantation has been reported to occur more commonly after self-expandable aortic valve implantation than balloon-expandable valve.
An 86-year-old woman treated by transcatheter self-expandable aortic valve implantation had acute coronary syndrome 3 months after the procedure. Emergent coronary angiography showed decreased blood flow in the left coronary artery. Balloon angioplasty between the valve frame and the left coronary cusp was performed, and her ischaemia resolved. Contrast-enhanced computed tomography showed a commissural post of the supra-annular valve overlying the left coronary cusp, and serial computed tomography showed the valve frame expanding over time. She received coronary bypass grafting using saphenous vein grafts for the left anterior descending and left circumflex arteries. Four months after surgery for the left anterior descending artery, the patient had recurrent chest pain, and computed tomography showed a graft occlusion in the left anterior descending artery. Shortly afterwards, she died of sudden cardiac arrest.
In this report, we describe delayed Valsalva obstruction after transcatheter self-expandable aortic valve implantation, which can be detectable by serial computed tomography. The sealing of a coronary cusp by a commissural post of the valve may be one of the causes of delayed coronary ischaemia after transcatheter self-expandable aortic valve implantation.

Elucidating the cause is essential for early directed therapy and prevention of complications. We present two cases of ventricular cystic masses, one in each ventricle, after myocardial infarction (MI) and ventricular septal rupture (VSR), respectively.
Patient 1 is a 58-year-old male with left brachio-facial stroke and evolved anterior MI. A left ventricular (LV) cystic thrombus was seen on transthoracic echocardiogram (TTE) and cardiac magnetic resonance (CMR) imaging. He was started on anticoagulation with reduction in thrombus size 11?days later. Patient 2 is a 67-year-old male with evolved anterior MI, severe LV systolic dysfunction, and normal right ventricular (RV) function. He was readmitted two weeks later with fever, heart failure, bacteraemia, and septic pulmonary emboli. Transthoracic echocardiogram showed biventricular systolic dysfunction and a RV cystic mass associated with a partial VSR. He was treated with anticoagulation and antibiotics. Repeat TTE 5?weeks later revealed near resolution of the cystic mass and complete VSR. Cardiac magnetic resonance confirmed these findings and also showed a localized mid-septal transmural infarction at the VSR site. He underwent percutaneous coronary intervention to the left anterior descending and circumflex arteries, and percutaneous VSR closure with a muscular ventricular septal defect device later.
Our two cases demonstrate that ventricular thrombi can present as cystic masses after MI and VSRs. Infectious, vascular, or oncogenic causes should be considered in the appropriate clinical context. Early diagnosis and treatment is essential to prevent embolic complications, and secondary infection.

Eosinophilic infiltration of the myocardium is often the consequence of a systemic disorder but can remain unexplained in up to a third of patients. The disease course can range from mild to fulminant myocarditis and mortality remains high for fulminant cases.
A 42-year-old male was admitted for cardiogenic shock. He presented in another hospital with fever, low blood pressure, diffuse electrocardiogram-abnormalities, and elevated troponin T (4.5??g/L; reference &lt;0.013??g/L) levels. Coronary angiography was unremarkable. Mechanical circulatory support with the ImpellaCP device was initiated. Since fulminant myocarditis was suspected and magnetic resonance imaging was not feasible in urgency, an endomyocardial biopsy was performed. He transiently developed right ventricular failure after Impellaimplantation, requiring the re-institution of an inotropic agent. Biopsy showed eosinophilic myocarditis, even though there was nosone and an angiotensin-converting enzyme-inhibitor resulted in rapid improvement. Awake mechanical circulatory support with the ImpellaTM device proved feasible and might have helped by unloading the left ventricle, as was reflected in an immediate decrease in troponin levels, even before methylprednisone initiation.From asymptomatic patients to severe acute respiratory distress syndrome, COVID-19 has a wide range of clinical presentations, and venous thromboembolism has emerged as a critical and frequent complication.
We present a case of a 69-year-old man with a clinical presentation of massive-like pulmonary embolism (PE) overlapping with severe COVID-19 pneumonia. The diagnosis was made based on hypotension, severe oxygen desaturation (33%), and right ventricular dysfunction (RVD). We used alteplase and low-molecular-weight heparin, obtaining immediate clinical improvement. Also, we identified an extremely elevated D-dimer (31.2?mcg/mL), and computed tomography pulmonary angiography (CTPA) revealed an unexpected low thrombus burden and a crazy-paving pattern. Considering this, we decided to discontinue the alteplase. Therefore, the mechanisms of pulmonary hypertension and RVD could be multifactorial. Despite the patient's respiratory status worsening and ongoing mechanical ventilation, biomarkers kept lowering to normal ranges.
